WHIP FOR MIXING MACHINES.

Aplieation led Haren 2,

To all 'whom A'it may conce/m.:

Be it known that I, PAUL S. WARD, a 'citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of 0hio,have invented certain new and useful Improvements in Whips for MixingMachines, of which the following is a s ecication.

y invention relates to whips used in l@ mixing machines in the bakersart, and is especially useful in so-called cake mixing machines formixing the batter or dough,

for cakes and' the like, but is especially designed for beating eggs andmixtures of w light consistency.

It is the object of my invention to provide 'a whip of novelconstruction which has a raising or lifting eiect upon the material;further, to provide a whip of novel con- 2@ struction which can be madein large sizes employing resilient wires andibe of rm construction;further, to provide a whip of novel construction in which' the wires arereleasable and in which new wires may be readily substituted; and,further, to provide a whip ofnovel construction in which the wiresareheld in place by means resisting their elasticity due to relativearrangements of the wires and holes for receiving the m same.

The invention will be further readily understood from the followingdescription and claims, and from the drawings, in which latter:

much of an exempliying mixing machine, in which' my improved device islemployed,

as is necessary to illustrate my invention.

Fig. 2 is an enlarged side elevation of the m whip. g

Fig. 3 is a plan view of the same.

Fig. 4 is ahorizontal section of the same, taken on the line 4 4, ofFig. 2.

Fig. 5 is a horizontal section ofthe same,

M taken on the line 5 5, of Fig. 2.

Fig. 6 isa bottom view of my improved device; and,

Fig. 'I is a vertical section of the same,

taken on the line 7 7, of Fig. 3, partly.

In the exemplifying machine there is a column 11 which supports avertically movable slide 12, adjustable up and down on Fig. 1 representsa side elevation of so 1928. Serial No. 622,284.

rods 13 by means of an adjusting screw 14, suitably operated. The base15 has a bowlring 16 swingable thereon on a pivot 17. Thev bowl-ringreceives a bowl 18 for containing the material to be mixed or beaten.

The whip, exemplified at 21, is arranged to rotate in the bowl Vand' tohave movement in'an annular path about the inside of the bowl.

The whip is arranged to be suitably releasably secured to a whip-shaft22, as by means of a bayonet slot and pin connection, of which the ins23 arelocated on the head 24 of the whip and the slots 25 are located 1na socket-piece 26, secured to the lower end of the whip-shaft. t

The whip-shaft is journaled in a bearing 31 of a planetarybearing-member 32 secured to the lower end of a drive-shaft 33journaled' in a bearing 34 in the slide, and driven in suitable mannerat selective speeds by means of suitable speed-changing mechanism. Apinion`35 is fixed to the Whipshaft, and meshes with an internal gear36, ixed to the slide. Rotation of the driveshaft 33 causes sweepingrotation of the bearing-member 32 about the axis of the drive-shaft, andtravel of the pinion about the inner toothed periphery of the internalto the whip about the inside of the bowl.

The machine parts are shown and d'escribed for a proper understanding ofmy invention, which relates to the whip, and to emphasize the heavyduties to which a whip of this character, especiall the larger sizesthereof for mixing or beating material having a bulk of a number ofgallons, are subjected.

The whip comprises a head, exemplilied at 24, from which a stem 38depends, the stem being shown lixed to the head by having threaded'connection 39 therewith, and being locked in place by a nut 40.

The lower end of the stem is provided with holes,exempliied at 41, 42,43., 44, 45,

46, 47, 48., 49. The holes `are arranged step- `wise, one above theother, 'and are also preferably arranged in relative. angular relationabout the axis of the stem. The holes are shown extending through thestem.

The head is provided with holes 51, 52, 53, 54, 55, 5e, 57, 5s, 59 ande1, e2, e3, e4, e5,

gear, imparting rotation and annular travel 66, 67, 68, 69. These holesare arranged' about the stem and arev shown as extending parallel withthe axis of rotation of the stem, but are preferably respectively inotlset angular relation to their mating holes 41', 42, 43, 44, 45, 46,47, 48 and 49 respectively.

Wires 71, 72, 73, 74, 75, 76, 77, 78, 79, which are preferably resilientwires like piano wire, extend between the lower end of the stem and thehead, being bulged outwardly as shown at 81, near their lower ends, andbent inwardly, toward the axis of the whip, as shown at 82, above saidoutward bulges. The lower portions of the wires are shown received inthe holes in the lower portion of fthe stem, and the upper ends of thewires are received in the holes in the head.

The number of wires and holes are selective. f

The -lower portions of the wires preferably form loops 83, the bights 84of which are locatedl in the holes in the stem.

The relationsof the lower portions and the upper ends of the wires tothe holes in which these are respectively received is prefeiably such,that the wires are subjected to torsion or bending or both between themating holes, so as to hold the wires in their holes by the tension ofthe wires. This is exemplified as accomplished by arranging thelocations of the holes in the stem or the directions in which theyextend in angularly offset relation to the holesl in the head, asexemplified by the angle 86, or by-having the holes in the lower endofthe stem and in the head extend at relative angles `to each other, orby having the wires of such length and form as to exert endwise pressurein the holes.

The direction of rotation of the whip is exemplified by the arrow 87.

The lower ends of the wires are relatively helically arranged about thelower end of the stem, with the result that, when the whip is rotated,it has a raising or lifting effect upon the material being operatedupon. An upwardly swirling motion is also imparted to the material byarrangement of the lyvires in inclined position in their rotary pat s.

A thorough vmixing and beating of the material, and a thorough inclusionof all the material to the mixing and beatingI action of the whip, andthe drawing of all particles of the material into the vortex formed bythe whip is thus assured.

In my improved device, further, the wires are readily insertable inassembling the whip and are readily renewable by replacement, making itextremely convenient for substituting worn, marred or broken wires bynew ones.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is:
